Biochemical Profiling

Biochemical profiling refers to the systematic analysis and categorization of cannabis plant chemistry—including cannabinoids, terpenes, flavonoids, and other secondary metabolites. Rather than a strain family or genetic lineage, biochemical profiling is a laboratory and breeding methodology used to document the chemical composition of cultivars and landraces. Breeders and researchers use profiling data to identify chemotype patterns, track trait inheritance, and select parent plants for targeted crosses. Modern profiling techniques include gas chromatography (GC) and liquid chromatography (LC) to measure cannabinoid and terpene ratios with precision. Understanding biochemical profiles helps breeding programs maintain consistency, explore genetic variation, and support reproducible cultivar development across generations.

Breeders use biochemical profiling to select parents that express desired cannabinoid ratios (THC:CBD balance), specific terpene blends, or novel minor cannabinoids. Profiling data also enables breeders to verify F1 and F2 generation chemistry, identify chemotype stability, and document how environmental factors influence plant biochemistry across growing cycles.
